By sequestering these ions, it inhibits critical bacterial enzymes, most notably RNA polymerase , which prevents bacteria from synthesizing proteins and replicating.
Nitroxoline is particularly effective at reducing the density of bacterial biofilms (slimy layers that protect bacteria) by chelating the iron and zinc necessary for biofilm stability. Medical Uses and Efficacy nitroxolin
Unlike many common antibiotics that target cell walls or DNA replication directly, nitroxoline works as a . By sequestering these ions, it inhibits critical bacterial
It binds to essential divalent metal ions—such as magnesium ( Mg2+cap M g raised to the 2 plus power ), manganese ( Mn2+cap M n raised to the 2 plus power Fe2+cap F e raised to the 2 plus power ), and zinc ( Zn2+cap Z n raised to the 2 plus power )—that bacteria require for enzyme function. It binds to essential divalent metal ions—such as
Nitroxoline is primarily indicated for lower, uncomplicated UTIs (cystitis). journals.asm.org
Nitroxoline is a urinary antibacterial agent primarily used for the treatment and prevention of uncomplicated urinary tract infections (UTIs). Although it has been used in parts of Europe for over 50 years, it has recently gained renewed attention due to its effectiveness against multidrug-resistant (MDR) bacteria and its unique, metal-chelating mechanism of action. Mechanism of Action
